New Nancy Guthrie note alleges video of Savannah Guthrie's missing mom

Another demand letter is emerging in the Nancy Guthrie kidnapping case.

TMZ reported Friday, June 26, that it had received a new letter from an individual previously in contact with the outlet, claiming they have video of one of the alleged suspects and Guthrie on a phone in a "secure location."

The person, who the outlet says has the same email and Bitcoin address as the person who emailed them weeks into the disappearance of Savannah Guthrie's mom, said there are allegedly two people responsible for Guthrie's kidnapping and that the video shows the "main guy."

The Pima County Sheriff's Department, which has been investigating the 84-year-old's Arizona disappearance, declined to comment; the FBI said it does "not comment on ongoing investigations." USA TODAY has reached out to NBC for comment.

According to TMZ, the note says the phone has video showing the 84-year-old on "the day that was probably her last" and photos of "both involved" as well as "names and addresses and age." The person told the outlet they will reportedly give up the password if they receive payment in Bitcoin.

USA TODAY has not viewed or authenticated the note. TMZ noted it has forwarded the email to the FBI, and told the person to send a screenshot of Nancy Guthrie in the video to prove its authenticity.

New Nancy Guthrie ransom note details emerge

The new note comes days after NBC News, ABC News and CBS News reported that a note received early on in the case claimed Nancy Guthrie was dead.

In the days that followed Guthrie's disappearance, unverified ransom notes containing alleged details about Nancy Guthrie's suspected abduction were sent to KOLD News, CBS' Tucson affiliate, and TMZ.

KOLD's note reportedly contained details about the home and what Nancy Guthrie was wearing that night, though the sheriff's department would not comment on its accuracy at the time, and the latter demanded millions of dollars in the form of Bitcoin to release Nancy Guthrie, with a deadline that came and went.

Savannah Guthrie said during an NBC interview in March that she and her family believe two of the many notes sent "were real."

"There are a lot of different notes, I think that came. And I think most of them, it's my understanding, are not real," Guthrie told Kotb in a "Today" interview segment released March 26. "But I believe the two notes that we received that we responded to, I tend to believe those were real."

Has Nancy Guthrie been found?

Nancy Guthrie has not been found. Guthrie, the elderly mother of "Today" show anchor Savannah Guthrie, was last seen on the evening of Jan. 31, when a family member dropped her off at her Tucson, Arizona, home after dinner. She was reported missing the next morning, and the Pima County Sheriff's Department launched an investigation, with the FBI coming on days later.
